Solution: Set up a private research institution unaffiliated with government similar to the historically successful Bell Labs. Here's how it worked before:

> "AT&T had a clear vision, that of offering universal connectivity to its customers. To achieve this well-defined long-term goal, the company consistently invested in R&D, planning ahead in terms of decades rather than years. Thanks to its government-supported monopoly, it could also afford to maintain the long-term thinking for half a century. Bell Labs was funded by what physicist and historian of science and technology Michael Riordan called “essentially a built-in ‘R&D tax’ on telephone service"
Google/Alphabet is essentially a monopoly these days with cash to burn, so they can certainly do the same thing. Cut the dividend to the shareholders and invest billions in independent R&D, just like AT&T did. Don't try to buy your way into federal agencies so you can direct their funds to private ventures.
Even better, change federal tax law such that the only way billionaires can escape a 90% income tax bill or corporations a 50% tax bill (highest tiers c. 1960) is to get a write-off by putting their money into such R & D efforts.
